POWDER 0R EXPLOSIVE MAGAZINE FOR WABfSHIPS.

Specification of Letters Patent.

To all whom, it may concern:

Be it known that I, CASSIUS CLAY PALMER, a citizen of the United States, residing at New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Powder or Explosive lilagazines for War-Ships, of which the following is a specification.

My invention relates to new and useful improvements in the powder or explosive magazines of Warships where it is desirable to employ mechanical refrigeration for regulating the temperature of the magazine, and the invention particularly contemplates improvements in the construction disclosed in an application for Letters Patent of the United States of John Edwin Starr, filed September 3,1912, Serial No. 718,177, for powder or explosive magazines for warships, ,the object being the provision of means whereby the roll or pitch of the ship will not cause water collected in the pan or pans disclosed in said application of John Edwin Starr to flow over the edges of the pans and thereby fall into the storage space by, and the invention consists in, the improvements to be more fully described hereinafter and the novelty of which will be particularly pointed out and distinctly claimed.

I have fully and clearly disclosed a preferred embodlment of my invention in the accompanying drawings to be taken as a part of this specification and wherein:

Figure 1 is a transverse vertical section through a magazine showing the drip pans provided with my improvements. Fig. 2 is a vertical central section through the magi zine taken at right angles to Fig. 1 and longitudinally of the pans. Fig. 3 is an enlarged sectional view on the same line as Fig. 1 showing the means for supporting the improved pans in place. Fig. 4 is a perspective view of an end portion of one of the pans including my invention.

Referring to the drawings by characters of reference, 1 designates a; horizontallydisposed deck plate which constitutes the roof or ceiling for the magazine, and 2, 2

designate the cross beams, usually flanged or channel beams, for supporting the deck plate 1. The magazine also includes end I walls 3, 3, side walls 4, 4:, and a floor 5 of metal plate. The beams 2, 2 are inclosed 1n heat insulating material 6, preferably cork, and the underside of the deck plate is ,covered by cork insulation 7 The side and I, end walls and floor of the magazine are also 1 insulated by cork slabs 8.

The beams 2, as shown, project below the inner surface of the ceiling, and between E the same adjacent the ceiling are arranged coils or grids of piping 9, constituting conduits through which is circulated a refrigerant by asuitable apparatus. Beneath the deck beams, and supported therefrom, are placed pans 10 made of steel e'ach of which gis insulated on the inner face of its bottom by a layer of Water-proof heat insulating 1 material 11, such as a composition of ground :cork and pitchyto prevent the pans being chilled by the refrigerating coils below the dew point of the magazine and thereby causj ing the condensation ofmoisture on the un- 1 derside of the pan. As shown, the pans are each preferably oblong in plan View and are provided with upstanding side flanges 12, and end flanges 13, which retain any moisture which may collect in the pans. The pans are so arranged that the space between cach two adjacent deck beams is jbridged by a. pan, and each pan is so ar- ;ranged that its longitudinal side flanges 12 contact the cork covering 6 of the deck I beams throughout the length of said flanges, so that the said flanges make an air and fluid-tight joint between the sides of each "pan and the insulation covering the deck beams, each pan, with the deck beams and the ceiling, forming an air duct across the upper end of the magazine. The upper edges of the longitudinal flanges 12 of the pans are inclined lengthwise relative to the bases of said flanges so that, when the pans are secured in place to form the air ducts, the bottoms of the pans will be inclined from one end to the other. The pans 10, as described, are preferably of a length less than the distance from wall to wall of the magazine, taken lengthwise of the deck beams, so that spaces 14, 15 are provided at the ends of the pans providing respectively an inlet and an outlet to each of the air ducts formed by said pans, the lower ends of the pans being eachprovided with a de- 'pending flange 16 forming with the adja- Patented Nov. 18, 1913.-

cent wall of the magazine an outlet or downtake passage 17 which, with the incline of the pan, facilitates the movement of the air through the air ducts.

The pans may be secured in place in any suitable manner, preferably so that a tight joint will be formed between the side flanges of the pans and the beams 2, as above set forth. The means employed consists of-U- bolts, the legs 18 of which depend from the beam, one leg of each bolt being passed down through an opening 19 in the flange of the deck beam, and the other leg being passed outside the edge of said flange as shown, so that the bolts are suspended by the portion 20 thereof connecting said legs bridged over the flange of the deck beams. One leg of each of said U-bolts passes down through a vertical tube 21 secured within the pan adjacent the sideflanges thereof, the lower end of the :tube being brazed to the bottom of the pan so as to provide a moisture-proof joint between the tube and the pan. The lower end of the tube opens through a hole 22 in the bottom of the pan, and when in place the lower threaded end 23 of the bolt passes through said hole and projects below the bottom of the pan where it carries a nut 24:. By screwing the nut up on the bolt the pan is moved toward the deck beams and the flanges and upper ends of the tube 21 moved positively against the insulation of the deck beam so as to form a fluid-tight joint therewith. It will be noted upon examination of Figs- 1 and 3 of the drawings that each U-bolt serves to support the adjacent edges of two adjoining pans.

The edges of the pans which abut the side walls of the magazines where there is no deck beam are supported by brackets 25 embedded in the insulation of the side wall and projecting horizontally into the magazine, upon which bracket the edge portion of the bottom of the pan rests and is sup ported, being secured to the bracket by a headed bolt 26 let down through a tube 21 as heretofore described and said bracket and secured by a nut 27 on its lower threadedare locatedat both ends'of the pans so that the pans will be properly drained at all times irrespective of the pitch and 'roll of the ship.

All of the above constitutes broadly, the invention of the said John Edwin Starr and has been repeated here only in order that the improvements constituting my invention may be more readily understood. It will be understood that the function of the pans is not only to form air duets with the deck plate, the side walls and the supporting beams, but to catch any water which may drip from the refrigerating coils. Under an amount of water might collect in the pans that it could not be carried off fast enough by the drains from the pans, and thepitch and toss of'the ship might cause the water to splash over the end flanges of the pan or pans and fall upon the contents of the magazine which, of course, would result in the deterioration ordestruct-ion of the explosives. My improvements especially contemplate means which will cause i the even distribution of the body of liquid in the pan so that no great amount of the water may rush to one end of the pan sufflcient to flow over the end flange thereof. This means-comprises a plurality of partitions orbaflles 29 arranged parallel to each other at suitable intervals lengthwise ofthe pan, and extending transversely of the latter parallel to each other. These partitions or baffles may consist of strips of sheet metal having vertical portions 30, brazed pan and shown as embedded in the insulation covering the bot-tom of the pan, the upper portions of the baffles being inclined transverse center of the pan being inclined toward said center. The baflles are preferably of such length that their ends are spaced from the longitudinal side flanges of the pan, as shown at 32. By this arrangement the pan is divided intoa plurality of compartments communicating with each other at their ends, and each adapted to icontain a portion of the fluid in the pan.

The baflles are preferably provided with by means of which communication is established between the-compartments of the pan in addition to the spaces 32 at the ends of the baflles, said perforations being preferably arranged on, or adjacent to, the juncture of the inclined portions of the baffles with the vertical parts thereof and the insulation at the bottom of the pan. By this arrangement, when the ship pitches or rolls, 1 the water contained in the pan cannot flow over the tops of the baflies, but will flow baflies, and said perforations, down the inclined bottom of the pan toward the drains 28, located respectively at the opposite ends thereof. In other words, the partitions or .batfles prevent the water confined in the compartments between the same from rushing suddenly toone end or the other of the pan and accumulating at one end thereof, in sullicient volume to overflow the end flange, but the spaces at the ends of the battles and certain circumstances it is possible that such or otherwise secured to the bottom of the perforations 33 spaced lengthwise thereof.

through the spaces 32, atthe ends of the laterally, as at 31, those, on each side of the 0. c. PALMER.
